What is usually the first step for a GMDSS...

🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) automatic distress alerting functions • How Inmarsat ship earth stations are designed to quickly send distress alerts with minimal operator action • Difference between sending an automated distress alert and making a follow‑up voice Mayday call

💭 Think About

• Ask yourself: in a real emergency, what action would equipment designers want the operator to take first to get the distress alert into the system as fast and reliably as possible? • Which of the choices sounds like an automatic, standardized alerting action, and which ones sound like later, follow‑up communications once a link is established? • Think about the typical layout of modern Inmarsat terminals: what clearly‑marked control is provided specifically for distress priority?

✅ Before You Answer

• Identify which option represents an immediate, single‑action alert that does not depend on talking to an operator first • Eliminate any option that requires a successful voice connection or detailed voice procedure before an alert is registered in the system • Verify which step would be common to all Inmarsat distress calls, regardless of which Coast Earth Station (CES) you are trying to reach
